That looks awesome! I have a new 135 we are setting up this weekend and I am going to do something similar--I found a ton of really nice terra cotta pots for .25 each.
I absolutely love the look of your tank. The elepants are cool too. I tried the clay pots with my Oscars and they totally destroyed them, ripping the plants up and pushing the pots around so their tanks are pretty bare now. That's how they like it, I guess.
